Support for multi sketch arduino projects is included in version 1.2
Large Arduino projects benefit from the visual studio intellisense. The ArduPilot project is a good example!
Everything you see below was automatically created when I opened the ArduPilot_25.pde in Visual Studio. The _core folder includes mappings to the Arduino board files, all other sketch files including .c and .h were also automatically linked into a new solution.
I opened the ArduPilot sketch, dropped down the master intellisense list (CTRL+J) and was amazed to see how much hard work has been invested into the ArduPilot system
